Just venting

So, I'm a 14 year old girl and have been going to a therapist for couple of weeks. I have been diagnosed with both anxiety (especially social anxiety) and depression. Today is Christmas, which is a day I normally associate with happiness, excitement, and spending time with my family. I really appreciate everyone in my family, but I don't feel love for them which makes me feel guilty. I've basically spent all day today in bed which makes me feel worse. I don't know why but i've never felt close to anyone except for non-related to me friends. My family has always been nothing but kind and loving yet my parents just feel like strangers to me. I feel like that's probably how my anxiety developed too (not understanding how to feel?)

Is this normal?
